variable within a variable

[Strat1979]

Is it possible to use a variable within a variable?

For instance, in this token, &mvt:subcats[18]:code; I would like to use a variable for the number (in this case 18).

So, is it possible to have it function like: &mvt:subcats[number]:code;

Using toolkit, I created a random number variable and tried using it like this:
<mvt:item name="toolkit" param="vrandom|number|l.all_settings:subcat_count" />
&mvt:subcats[number]:code;

However, no go.

Is there a way to do this?

Thanks.

When using Tool Kit in this way, 'number' is a global variable. Try this as your token:

&mvt:subcats[&mvt:global:number;]:code;

Hi Matt,

Thank you for the response.
Yes, I had already tried that. Here is the error message:
Fatal error in mm5/5.00/templates/s01/c51-footer.mvc @ [00000002:0000005c]: modules/component/cmp-cssui-pchdft.mv: Line 4: Array index must be positive integer

Check to make sure that &mvt:global:number; is outputting. If it isn't, you may need to check the variable being used to generate the random number.

It is outputting.
&mvt:global:number; does show a number value.

Can you post the function you are passing the global number into?

<mvt:item name="toolkit" param="vrandom|number|l.all_settings:subcat_count" />
&mvt:global:number;
<br>
&mvt:subcats[&mvt:global:number;]:code;

[Matt Zimmermann]

Are you using this within a Tool Kit function or is it just for displaying the particular code?

[Strat1979]

I am using it in a ReadyTheme Product Listing (carousel).
I have also tried it on the footer of a category page.
In both cases I do get a value for &mvt:global:number;

It looks like, at this time, without using something like Tool Belt, Miva will not render a variable within a variable like you are trying to do. You can see an example of how to use the assign function in Tool Belt here, see example 4 http://www.pcinet.com/p/toolbelt_docs.html#Assign

What if you tried something like this?

<mvt:eval expr="l.settings:subcats[g.number]:code" />

Thanks dcarver,

Tried it but the same error.
